Antiretroviral therapies stop the proliferation of HIV in the body to reduce the viral load. This greatly reduces the risk of transmitting the virus to more people. If both sexual partners are receiving antiretroviral therapy then the likelihood of transmission can be reduced by up to 96 per cent.

It's thought that antiretroviral therapy has saved nearly 8 million lives so far.

A Phase III clinical trial has found that people who do not respond to antiretroviral therapy can be treated with monoclonal antibodies.

Antiretroviral therapy has several side effects, such as anaemia, nausea and diarrhoea. Some patients do not respond to these therapies at all. Research has shown that monoclonal antibodies could soon be an alternative treatment option for people diagnosed with HIV.

The treatment has yet to be approved by the Food and Drug Administration in the US.

3. Antibody therapy could boost immune system to help patients off antiretrovirals

Antibody therapies could also help as an additional treatment to antiretrovirals. Monkeys that had the simian equivalent of HIV – SIV – had their viral load reduced to undetectable levels after receiving the antibody anti-alpha4/beta7 after receiving antiretroviral therapy.

The paper, published in the journal Science, found that after receiving the antibody once a fortnight for 32 weeks, high levels of SIV did not return in the monkeys when antiretroviral therapy was stopped.

The use of precise gene-editing technology in HIV research could hasten the search for a cure for HIV and Aids. Researchers at the University of California San Francisco used CRISPR-Cas9 technology to investigate human immune cells' resistance to HIV.

They found that mutations in two genes – CXCR4 and CCR5 – offered some protection to HIV. This research will now form the basis for further studies into whether this can be converted into an effective treatment.
